You've learned your first life lesson, little Otis. Life can sometimes feel like being doused in the face with pee, but - if you're lucky enough - your mum will be close at hand to wipe up the mess and then inform the internet about it (it's just one of the many joys of motherhood).

And, if your mum's lucky enough, you'll teach her a few things along the way too - like every man has, at sometime in his iife, peed on his own face.

See, you do learn something new every day. Don't say we don't learn ya anything!
